operant conditioning
Definition
Target type: biologicalprocess
Learning to anticipate future events on the basis of past experience with the consequences of one's own behavior. [PMID:14662373]
Operant conditioning, a fundamental principle of learning, describes the process by which an organism's voluntary behavior is modified by the consequences that follow. This learning mechanism is based on the association between an action and its subsequent outcome. The core principle revolves around the idea that behaviors followed by rewarding stimuli are more likely to be repeated, while those followed by aversive stimuli are less likely to occur.
Operant conditioning operates through the interplay of reinforcement and punishment. Reinforcement, either positive or negative, increases the probability of a behavior occurring again. Positive reinforcement involves the presentation of a desirable stimulus following a behavior, such as giving a treat to a dog for sitting. Negative reinforcement involves the removal of an aversive stimulus following a behavior, such as turning off a loud alarm by pressing a button. Punishment, conversely, decreases the likelihood of a behavior. Positive punishment involves presenting an aversive stimulus after a behavior, such as spanking a child for misbehaving. Negative punishment involves removing a desirable stimulus after a behavior, such as taking away a child's toy for disobedience.
Key components of operant conditioning include:
* **Reinforcer:** A stimulus that increases the probability of a behavior.
* **Punisher:** A stimulus that decreases the probability of a behavior.
* **Contingency:** The relationship between the behavior and its consequence.
* **Schedule of reinforcement:** The pattern of reinforcement delivery, which can be continuous or intermittent.
* **Shaping:** Gradually reinforcing successive approximations of a desired behavior.
Examples of operant conditioning are prevalent in everyday life. A child learning to say "please" to receive a cookie is an instance of positive reinforcement. A rat pressing a lever to avoid an electric shock illustrates negative reinforcement. A driver slowing down to avoid a speeding ticket exemplifies negative punishment.
Operant conditioning plays a crucial role in shaping behavior across diverse domains, including education, therapy, and animal training. It is a powerful tool for understanding how learning occurs and for influencing behavior in desired ways.
